These are FFP ???SWFA SS HD 1-6X24 is considered real solid, if 1-6 power & 24mm would meet your needs. Capped turrets.
The rail thing is why I wouldn’t ever mount one of these on my 375. I don’t want to do anything that would cover the ejection and loading area on my dangerous game rifle. I don’t even use extended bases.Reasonable choice, although like others have said, the SHV would probably be sufficient and save you some money. With either though, you are gonna need a rail. Both of those scopes are way too short to put on a .375 length action without a rail.
